The image contains two diagrams, the left diagram, titled "A wind turbine," features a wind turbine with labeled parts including rotor diameter (40-90m), hub height (50-80m), and generator (1.5-5MW). Below the turbine, there is a small building labeled electrical systems. The turbine is set on flat terrain with a single tree and vehicle close by. An arrow indicating wind goes through the rotor. The right diagram, title "Wind turbines: optimum locations," presents the same wind turbine with labeled rotor diameter (40-90m), hub height (50-80m), and generator (1.5-5MW). This turbine is placed on a hilly terrain with variable heights indicated (20-80m), a coastline depicted on the right, and a house and tree on the lower left side. An arrow indicating wind is pointing towards the rotor, originating from the higher elevations of the hill.
Given the complexity of the image, the above description may not be entirely accurate.

The diagrams clarify where wind turbines should be situated and what they look like.
According to the diagrams, there are three possible locations for a turbine. A large industrial turbine would be built high up on a hillside where the wind is strongest, and these turbines can produce 1.5 megawatts of power. On the other hand, smaller turbines that produce 100 kilowatts of power for domestic use can be found on rooftops. The third possible position is in the sea. Here, there is less impact on the countryside, but winds can still be very strong.
While the locations may be different, the turbines themselves all have the same special shape. They consist of a tall tower made of strong steel and on top of this there are three blades made of fibreglass or wood. The turbines are controlled by a computer which can alter the direction and angle of the blades accompanying to the information it receives from a sensor.
Clearly, most wind turbines are genuinely large, and all turbines need to be exposed to a lot of wind.
